Abstract Scope |
Improvements to nanoindentation techniques have allowed for faster data collection and expanded methods for data interpretation. Techniques, such as Nanoblitz 3D, have allowed for mapping material properties of a selected sample area at high speeds. In order to create these maps, the indent spacing must be sufficiently distanced so that previous indents do not influence subsequent indents. However, the indents must be close enough to understand the local variations of the sample. Previous work has been done to find the optimal ratio of indent spacing to indent depth (d/h ratio) for bulk materials. This work will focus on how nanoporous structures influence the d/h ratio. Nanoporous gold samples are created and coarsened to various ligament sizes in order to be tested at multiple d/h ratios to identify the optimal spacing. Preliminary findings have shown that the ideal d/h ratio for nanoporous structures is similar to bulk metallic materials. |
